Advantages of Synthetic Oils Compared to Mineral Oils
Synthetic Gear Oil vs. Mineral Gear Oil? The Difference After 8,000 Hours of Operation.
The quality of lubricant used in industrial gear systems not only reduces friction but also directly impacts gear surface protection, energy efficiency, maintenance costs, and equipment lifespan .
In gearboxes operating particularly in heavy industry, iron and steel, cement, mining, energy and continuous production facilities, selecting the correct gear oil is critical for long-term operational reliability.
So, what difference does it make between synthetic and mineral-based gear oil after long periods of operation?
Differences that may appear on gear surfaces after an 8,000-hour operating period can clearly demonstrate the impact of lubricant technology on equipment performance.
What changes occur on gear surfaces after 8,000 hours?
Gear systems operate under continuously high contact pressure, friction, temperature, and mechanical loads during operation.
Over time, improper lubrication conditions;
wear,
surface roughness,
pitting and micropitting,
scuffing,
Oxidation-related sediment
temperature increase,
tooth profile deformation
This can lead to problems such as these.
The base oil composition and additive technology of the lubricant significantly influence the rate at which these problems occur.
In the Use of Synthetic Gear Oil
High-quality synthetic gear oils aim to create a more stable oil film, especially under prolonged and heavy operating conditions.
When the appropriate product and correct viscosity are selected, synthetic oils;
to create a stronger oil film,
to reduce friction,
better protection of toothed surfaces,
maintaining viscosity stability at high temperatures,
to increase oxidation resistance,
extending oil change intervals
It can contribute.
Over long operating periods, such as 8,000 hours, these properties can manifest as more controlled wear on the gear surfaces and a smoother operating surface .
Long-Term Operation in Mineral Gear Oils
High-quality mineral gear oils are successfully used in many standard industrial applications. However, under demanding operating conditions such as high temperatures, continuous heavy loads, high cycle times, and long oil change intervals, the oxidation resistance and viscosity behavior of the base oil become more critical.
As a result of prolonged work with unsuitable products or working conditions;
Consequences such as weakening of the oil film, increased surface wear, formation of oxidation products, increased operating temperature, and increased maintenance requirements may occur.
Therefore, the evaluation should not be based solely on the distinction between "synthetic or mineral"; it should also consider application conditions, load, temperature, speed, gearbox design, and OEM requirements .
Key Advantages of Synthetic Gear Oils
Synthetic base oil technologies can offer significant advantages, especially in heavy-duty industrial gearboxes.
Feature | Synthetic Gear Oil | Mineral Gear Oil |
High temperature performance | High | Application dependent |
Oxidation resistance | Usually higher | It may be more limited. |
Oil film stability | High | It depends on the working conditions. |
Low temperature fluidity | Generally better | More limited |
Potential oil change interval | It could be longer. | It could be shorter. |
Energy efficiency potential | It could be higher. | Standard |
Suitability for harsh working conditions | High | Product dependent |
Initial product cost | Higher | Lower |
However, it is not accurate to look only at the purchase price of the oil here.
For industrial businesses, the main parameter to consider is the total cost of ownership — TCO (Total Cost of Ownership).
Could More Expensive Oil Lead to Lower Operating Costs?
Yes, it can provide that with the right application.
The cost of oil in an industrial gearbox is often quite low compared to the costs of unplanned downtime, gear damage, or bearing replacement.
For example, thanks to a synthetic oil;
If the oil change interval can be extended,
If the operating temperature can be lowered,
If gear wear can be reduced,
if improvements in energy consumption can be achieved,
If the risk of unplanned maintenance can be reduced
Even if the initial purchase cost is higher, the total operating cost can be significantly reduced.
Therefore, lubricant selection should be considered not just a decision to purchase a consumable , but also a maintenance and equipment reliability strategy .
Is it possible to switch to synthetic oil in every system?
No.
Before switching to synthetic oil, the system must be technically evaluated.
The main things to check are:
Gearbox manufacturer's oil specification
ISO VG viscosity class
Operating temperature
Environmental temperature
Gear type
Load and speed
Felt and elastomer compatibility.
Miscibility with existing oil
Paint and gasket compatibility.
Filtration system
Condition of the existing oil
Especially when switching from mineral oil to PAO, PAG, or another synthetic base oil, the compatibility of the oils must be checked.
Some systems may require a flush/system cleaning before an oil change .
Why is Fat Analysis Important?
It is not sufficient to evaluate the performance of a lubricant solely by looking at its operating time.
It is recommended that the oils used in professional maintenance programs be analyzed periodically.
Main analysis parameters:
Viscosity: Indicates whether the oil remains within the correct viscosity range.
Acid Number – TAN: Helps in assessing the level of oxidation.
Water content: Indicates moisture or water contamination in the oil system.
Particle analysis: Provides information about system cleanliness.
Wear metals: Iron, copper, chromium, and other metals can provide important data about equipment wear.
FTIR analysis: Can be used to monitor oxidation and fat degradation.
When these data are evaluated together, important information can be obtained not only about the oil but also about the mechanical condition of the gearbox .
The Importance of Gear Oils in the Iron and Steel Industry
Steel and iron plants are among the sectors where lubricants face the most demanding working conditions.
Gearboxes;
high temperature,
heavy load,
vibration,
dust,
This,
metal particles,
24/7 operation
They may be exposed to harsh conditions such as these.
In rolling mills, conveyor systems, cranes, fans, pumps, crushers, and heavy-duty gearboxes, selecting the correct lubricant directly affects production continuity .
Therefore, in iron and steel plants, the lubrication program should not be evaluated solely as a product change, but as a holistic approach encompassing oil analysis + equipment monitoring + correct product selection + technical service .
Result: Proper Lubrication, Longer Equipment Life.
The performance differences observed after 8,000 hours of operation clearly demonstrate the importance of lubricant selection for long-term equipment condition.
Properly selected high-performance synthetic gear oils;
This can contribute to controlling wear, protecting gear surfaces, optimizing maintenance intervals, reducing energy losses, and extending equipment service life.
However, the most appropriate lubrication solution must be determined specifically for the operating conditions of each facility.
